Kampala ( Uganda ) und Jinja (Busoga) in sumpfigen Talböden. Unspecified number of ♂ and ♀ . The MHNG collection contains five specimens in alcohol in two jars. The first jar (MHNG-ARTO-18574) contains a vial holding a broken specimen and a smaller vial holding dissected parts including gonopods. A typewritten label in the larger vial states that Hoffman selected this specimen as lectotype in 1972. The original identification label in the jar has “ types ! Kampala J. Carl” written on it, indicating that the specimen is part of the type series. An undated typewritten label states that Hoffman identified the specimen as Ectodesmus tesselatum (Carl) . The second jar (MHNG- ARTO-18575) contains a vial holding four specimens , two with pins running the length of the body. An original identification label in the tube has “Marsch bei Kampala ” written on it, indicating that the specimens are part of the type series. A typewritten label in the jar states that Hoffman selected these specimens as “lectoparatypes” in 1972. The identification label in the jar has “Selon Hoffman Paradoxosomatidae Ectodesmus tesselatum (Carl) ” typewritten on it. The lectotype designation does not seem to have been formally published and all of these specimens are therefore syntypes . There are two syntypes in the ZMUH ( Weidner, 1960 ) and two in the MCZL . Habrodesmus tesselatus (Carl, 1909) , Paradoxosomatidae
